Purpose and fitment for Mercedes Vito / Viano W639

The glass has been constructed with the Mercedes Vito and Viano W639 body in mind, taking into account the geometry of the rear part of the vehicle and its characteristic side line. The placement on the vehicle is the rear right side, which means the component fits the right side window opening in the rear zone of the body. As a result, installation is predictable, maintaining factory mounting points and proper sealing.

Technical characteristics of the AS2 glass

The AS2 marking indicates glass with controlled light transmission, intended for use in the side and rear glazing of a vehicle. This type of glass:

• ensures adequate visibility for the driver and passengers,
• reduces excessive interior heating,
• meets safety requirements regarding damage resistance and breakage patterns.

Thanks to this, the glass works well both in daily operation of a commercial vehicle and in passenger versions, where the comfort of those traveling in the rear part of the cabin is important.

Benefits of using original automotive glass

Choosing an item from the Automotive glass category dedicated to a specific generation of Mercedes allows you to maintain the structural consistency of the body. The original rear right window:

• maintains the proper rigidity of the side body section,
• ensures correct adhesion to seals and trim strips,
• minimizes the risk of leaks and unwanted wind noise while driving.

Additionally, the use of glass with the correct optical parameters reduces image distortion, which is important when observing the surroundings by passengers and during maneuvers performed using visibility through the rear side window.

Used condition – a reasonable economic choice

The presented glass is a used item, which is a beneficial solution for users looking for a proven component at a reasonable price. This type of part allows you to restore full functionality of the glazing after mechanical damage or a collision, without the need to invest in a new element. In many cases, it is an effective way to keep the vehicle in good technical condition while maintaining control over repair costs.

Mounting zone and practical application

The placement of the glass in the rear, right part of the body is important for both safety and the ergonomics of vehicle use. This element:

• affects the illumination of the cargo or passenger space,
• enables better control of the surroundings on the right side of the vehicle,
• constitutes an integral part of the side body structure.

A properly selected rear right window helps maintain the factory character of the vehicle, which is important both in fleet operation and in the case of privately used cars.
